Run this through pandoc, then use your favorite PDF editor to "crop" the pdf down to just the table.
|
|
This is wacky, but seems to be the best way to get the table to fit in the document margins.

Summary of Changes
|
|
------------------
|
|
|
|
**Cryptol version 2** | **Cryptol version 1** | **Summary**
|
|
---------------------------- | -------------------------------- |--------
|
|
`[ False, True, True ] (==3)` |`[ False True True ] (== 6)` | Big-endian word representation
|
|
`[ 1, 1, 2, 3, 5 ]` |`[ 1 1 2 3 5 ]` | Commas separate sequence entries
|
|
`x = 1` |`x = 1;` | Uses _layout_ instead of `;`'s and `{`'s
|
|
`[ x \| x <- [1 .. 10] ]` |`[\| x \|\| x <- [ 1 .. 10] \|]` | Cleaner sequence constructor syntax
|
|
`f : {a,b} a -> b` |`f : {a b} a -> b` | Commas separate type variables
|
|
``take`{1} xs`` |`take(1, xs)` | First-class type parameters
|
|
`x ^^ 2` |`x ** 2` | `^^` for exponentiation
|
|
`<\| x^^2 + 1 \|>` |`<\| x^2 + 1 \|>` | Polynomial exponentiation now uniform
|
|
`[0 ..]:[_][8]` |`take(255, [0 ..]:[inf][8])` | Both produce `[0 .. 255]`
|
|
`[0 ...]:[inf][8]` |`[0 ..]:[inf][8]` | Both produce `[0 .. 255]`(repeated)
|
|
`[9, 8 .. 0]` |`[9 -- 0]` | Step defines decreasing sequences
|
|
`&&, \|\|, ^` |`&, \|, ^` | Boolean operator syntax
|
|
`(1,2,3).0 (== 1)` |`project(1,3,(1,2,3)) (==1)` | Tuple projection syntax (and 0-based)
|
|
`property foo xs=...` |`theorem foo: {xs}. xs==`... | Properties replace theorems (see below)
